Specifically, in the present embodiment, the inter-row air conditioners in the first and second micro modules 10 and 20 are arranged in such a manner as to uniformly distribute the cold air formed by the inter-row air conditioners in the cold aisles, as shown in fig. 1.
The redundant inter-row air conditioners 13 are one or more inter-row air conditioners configured based on the standard inter-row air conditioner configuration number, the standard inter-row air conditioner number is the number of inter-row air conditioners configured by designers according to the power of the micro module and an industry standard, the redundant inter-row air conditioners increase the reliability of the refrigeration system through multiple backups, and in order to avoid excessive energy consumption, a configuration mode of adding one redundant inter-row air conditioner is adopted in the embodiment. In the present invention, a micro module in which the redundant air conditioners 13 are disposed is referred to as a first micro module 10, and a micro module in which the redundant air conditioners 13 are not disposed is referred to as a second micro module 20.
The side wall surfaces of the outer shell of the micromodule are butted with each other, the cold channels of the first micromodule 10 and the second micromodule 20 are corresponding to each other, and a communicating hinge 30 is arranged at the position of the butted side wall of the first cold channel 12 and the second cold channel 22, namely, the position of the formed connecting wall. The connected hinges 30 include a first hinge 31 and a second hinge 32, and the structure of the connected hinges is shown in fig. 1, in this embodiment, each of the first hinge 31 and the second hinge 32 includes a rotating structure and a hinge structure, the rotating structure includes a motor and a rotating shaft, the hinge structure is fixedly connected to the rotating shaft, an output shaft of the motor is fixedly connected to the rotating shaft, and the motor is fixedly disposed on the connecting wall, so that the first hinge 31 and the second hinge 32 can rotate, and the rotating directions of the first hinge 31 and the second hinge 32 are opposite. When the communicating leaflet 30 is closed, one side of the first leaflet 31 and one side of the second leaflet 32 are overlapped with the side wall of the micro-module outer shell, so that the communication between the first cold channel 12 and the second cold channel 22 is blocked, and when the communicating leaflet 30 is opened, one side of the first leaflet 31 and one side of the second leaflet 32 rotate along with the leaflet and are far away from the side wall of the micro-module outer shell, so that the communication between the first cold channel 12 and the second cold channel 22 is opened.
In particular, in the present embodiment, the direction of the opened first and second flaps 31 and 32 is toward the second cold aisle 22, and since the excess cold air enters the second cold aisle 22 from the first cold aisle 12, the flaps themselves may form a duct for the cold air to enter with the side wall of the cold aisle when the first or second flap 31 or 32 is opened, thereby reaching the vicinity of the malfunctioning inter-row air conditioner more intensively.
In addition, the opening angles of the first hinge 31 and the second hinge 32 can be adjusted according to the cooling capacity required by the second micromodule 20, and the required cooling capacity can be obtained according to the operating power of the second inter-row air conditioner 21 and the operating power of the ICT equipment in the second micromodule 20.
In addition, a temperature sensor is further provided in the second cold channel 22 of the second micro-module 20, and the temperature sensor can detect the temperature in the second cold channel 22, so as to determine whether the second micro-module 20 needs the supply of the external cold air.

The embodiment of the invention also provides a refrigeration scheduling method applied to the micro-module data center, which acquires the equipment state in real time through a controller and logically judges the following control commands, and specifically comprises the following basic judgment and control processes:
s1, detecting whether the second inter-row air conditioner 21 in the second micro module 20 has a fault;
s2, if the second inter-row air conditioner 21 fails and it is determined by the temperature sensor that the air temperature in the second cold air duct 22 of the second micro module 20 exceeds the set threshold, controlling the communicating flap 30 connected to the second micro module 20 to switch to the open state, and simultaneously opening the redundant inter-row air conditioner 13 in the corresponding first micro module 10;
s3, if the second inter-row air conditioner 21 has a fault and it is determined by the temperature sensor that the temperature of the air in the second cold air channel 22 of the second micro-module 20 does not exceed the predetermined threshold, controlling the communicating flap 30 connected to the second micro-module 20 to maintain the closed state.
S4, if the second inter-row air conditioner 21 has not failed, controlling the communicating hinge 30 connected to the second micromodule 20 to keep closed;
s5, if the second inter-row air conditioner 21 has not failed and it is determined by the temperature sensor that the temperature of the air in the second cold aisle 22 of the second micro module 20 exceeds the set threshold, controlling the communicating flap 30 connected to the second micro module 20 to switch to the open state, and opening the corresponding redundant inter-row air conditioner 13 in the first micro module 10.
On the basis, the controller can also detect and acquire the specific position of the failed second inter-row air conditioner 21 in the second micromodule 20, because the second inter-row air conditioners 21 are arranged on both sides of the second cold channel 22, when a certain second inter-row air conditioner 21 fails, the ICT equipment nearby the certain second inter-row air conditioner 21 is more prone to overheating, and at this time, after the controller acquires the relevant position, the controller can control a certain hinge in the communicating hinge 30 close to the position to open, for example, when the lower second inter-row air conditioner 21 fails in fig. 1, after the controller acquires the position, the controller can control the first hinge 31 on the left side or the right side to open, so that the cold air in the first micromodule 10 enters the second cold channel 22 and intensively reaches the vicinity of the failed second inter-row air conditioner 21.
In addition, on the basis of the control process, the load power of the ICT equipment in the first micromodule 10 can be obtained through the controller, because the operating conditions of the equipment are different, the load power of the ICT equipment between micromodules in the same micromodule data center may not be the same, when the refrigeration of the second micromodule 20 is insufficient, the communicating loose-leaf 30 connected with the second micromodule 20 needs to be opened through the control process to receive the cold air in the first cold channel 12, and at this time, the communicating loose-leaf corresponding to the first micromodule 10 with the lower load power can be selected to control by judging the respective load power of the first micromodule 10 at both sides of the second micromodule 20.
According to the micro-module data center and the corresponding refrigeration scheduling method, redundant inter-row air conditioners do not need to be arranged in each micro-module, the construction cost and the total energy consumption of the data center are reduced, meanwhile, the refrigeration effect of the data center can meet requirements, and equipment overheating is avoided.
The description of the above specification and examples is intended to be illustrative of the scope of the present invention and is not intended to be limiting. Modifications, equivalents and other improvements which may occur to those skilled in the art and which may be made to the embodiments of the invention or portions thereof through a reasonable analysis, inference or limited experimentation, in light of the common general knowledge, the common general knowledge in the art and/or the prior art, are intended to be within the scope of the invention.
